A E sTATES CHARLES H. TURNER, or WORCESTER,

LEY CAR COMPANY, or WORCESTER, cHUsETTs.

State of Massachusetts, have invented a new#k of which the foland useful Car-Ventilator,

y lowing is a specification.

This invention relates to a ventilator particularly adapted for use on passenger cars. Tt is essential that such ventilators be effective to induce a brisk circulation of air therethrough7 and also that they positively prevent entrance of rain or snow under all conditions of wind or weather.

Many of the usual types of ventilators fail to give satisfaction in this latter respect, as they do not adequately protect the passengers from moisture under certain conditions, and particularly when hard driving storms are accompanied by high winds.

It is the object of my invention to improve the construction of Such ventilators to the end that they may more effectively perform their ofice and that they may afford absolute protection to the passengers.

Vith this general object in view my invention relates to certain arrangements and combinations of parts which will be hereinafter' described and more particularly pointed out in the appended claim.

preferred form of my invention is shown in the drawings in which- Figure 1 is a perspective View of my improved ventilator;

Fig. 2 is a vertical sectional view taken along the line 2-2 in Fig. 1, and

Fig. 3 is a transverse sectional view taken along the line 3-3 in Fig. 1.

The ventilator shown in the drawings is of a twin or double form and is shown mounted upon the roof 10 of a passenger car. A circular sleeve or intake 11 is inserted in the roof of the car, and may be provided with a perforated cover 12 at its lower end. The intake communicates with lateral passages 13-13 which extend in opposite directions to the two separate outlet portions. The plate 14 which covers the lateral passages 13 may be reinforced by a rib 15 on its lower side, if so desired.

At their outer ends the passages 13 cornmunicate with inner vertical iues 16 which extend upward therefrom, and are covered by caps 17. These caps are spaced from the upper ends of the fiues 16 both vertically specification ofretters Patent H. TURNER,

A f f Patented Nov. 6, ,19317.I Application ledMay 26, 1916.- Serial No.- 100,128.l v y andlaterally, andthe edgeportions of the caps extend :downward below Vthe upper edges of the flues'16.`

The caps 17 areinclosed within outer verticalfiues 18', and the-space between eachv cap-17 and flue 18 is filled in with an open Y grille work or grating 19. This grille work serve to supportv the cap and to hold the same in the correct relation to the liues 16 and 18. The grille work-is formed of vertical members `having substantially the same depth as theedges of the cap 17, thus subdividing the outer flue into a plurality of separated passages of comparatively small cross section. This subdivision of the flue materially increases the effectiveness of ven tilators of this type, as is well known in the art.

The circulation of the air through my improved ventilator is clearly shown by the small arrows in Figs. 2 and 3. It will be seen that the air rising through the intake 11 passes to the right or to the left along the lateral passages 13 from which it passes upwardly through one of the inner flues 16, then downwardly between the flue 16 and the cap 17 and finally upward through the grille work 19 to the open air.

W'ith this construction it is absolutely iInpossible, under any conditions of weather, for rain or now entering through the grille work 19 to reach the interior of the car. Vhatever moisture enters through the grille work collects within the outer flue 18 and is 'taken care of by drainage openings 20 (gig. 1) at the lower outer edge lof the flue 1 end of the passages 13 is slanted sharply downward, as shown in Fig. 2, to conduct the drainage to the openings 20.

Having thus described my invention it will be seen that this ventilator is of a compact and serviceable formv and that the air currents are so directed that moisture will be absolutely excluded from the interior of the car. While I have shown a double or twin ventilator, it will be understood that the advantages of my invention may be equally well secured in a single ventilator such as would be produced by inserting a partition 22 in the device shown in Fig. 2, and omitting the construction shown to the right of said partition.

It will be evident that other changes and modifications can be made in my invention The partition 21 whichA closes the outer without departing from the spirit and scope thereof as set forth in the claims, and lf do not wish to be otherwise limited to details herein disclosed, but what l claim is A car ventilator comprising` an inner vertical flue, a cap supported above said flue and inclosingthe upper end thereof, said cap being` spaced from said flue both verti-v cally and laterally and having its edge portion extending below the upper open end of said Hue on all sides thereof, en outer vertical flue surrounding,` said cap and inner flue, and held in xed spaced relation to Copies of this petent :may be obtained for veteents each, by addressing said cup by grille work interposed between the cap and the outer Hue and secured to each of said members, and an imperforate bottom plate connecting said inner and outer lues at their lower ends, portions thereof being outwardly and downwardly inclined and said outer flue having drainage openings neer the lower outer edge thereof.

In testimony whereof l have hereunto set my hand.
